It is outright frustrating that I have spent an enormous amount of time trying to figure out why many expected operations just do not happen as the instructions are written/carried in a video. Following up on this new Active_PFC model & PID tuning. Local FAE pointed out that one should not start FRA from low frequencies but higher than hundreds if possible...well this trick surely worked but was it discoverable from documents? Could I have saved 100 hrs trying to figure it out? The example does not even mention this. Then the Instruction goes on to do the Estimator, obtain estsys1 data...all of which went fine with LF at 400 Hz . So far, the struggle for 1 week paid off- my data is the same as the example. I also could figure out how the drag-drop of the LTI data was working. Then you are told to go to PI-Current control block, to tune the PID.

Now I faced a brick wall. I simply do not get the Bode data displayed in the tuner tool as shown. Instead, I get an error msg at the bottom "could not find a system " or something like that. I thought maybe 2019b was the issue. So I installed R2019a. Same result: I can inspect the estsys1 data...but no plots at all. Why is it so incomprehensively convoluted to work with these tools with documentation spread all over? More precisely, how can I search for a reason for this problem & then a solution? If there are bugs in installations, should they not send fixes? Very annoying and frustrating. One more thing: they are pushing me to get "training" & consultant....why not put an effort in consolidating documentation &/or verifying models & analysis steps work as expected! Any help here will be highly appreciated.
